Explicitly defining fields on ModelSerializer overrides Model's parameters like verbose_name and validators
Imagine having a simple model like the one bellow: from utils.validators import name_validator class Customer(models.Model): name = models.CharField(verbose_name="Customer Name", validators=[name_validator]) email = models.EmailField(verbose_name="Customer Email") def __str__(self): return self.name Now if I explicitly define a filed on my serializer, both validators and verbose_name are lost. I can use label= and validatos= when defining the field on my serializer but I don't want to repeat myself. What if I have multiple serializer pointing to the same Model? class CustomerSerilizer(serializers.ModelSerializer): custom_field_name = serializers.CharField(source="username") class Meta: model = Customer fields = "__all__" Is there anyway to prevent this from happening? -
Wagtail - Override internal links in richtexteditor
Since I use wagtail headlessly the internal links get messed up due to them using the site-url listed in settings. Instead, I want to be able to override that same URL and point them to my frontend. This post talks a little bit about it in 2018, but I'm hoping this has changed? Wagtail: Is it possible to disable prepending internal link's with the site domain? For external links you'd do something like this to override it: class NewWindowExternalLinkHandler(LinkHandler): # This specifies to do this override for external links only. identifier = 'external' @classmethod def expand_db_attributes(cls, attrs): href = attrs["href"] print(attrs) # Let's add the target attr, and also rel="noopener" + noreferrer fallback. # See https://github.com/whatwg/html/issues/4078. return '<a href="%s" target="_blank" rel="noopener noreferrer">' % escape(href) Is it possible to do the same for internal links? E.g now since I use a multi-site setup my link looks something like: https://localhost.my-backend-api-domain.com/page/pagename I want it to look like this: https://my-frontend-domain.com/page/pagename -
Post only unique key value pairs to redis instance
I am POSTing a list of key values pairs to a redis_instance. I would like to first check if any of the keys/values I am posting to redis already exist to avoid having duplicate key value pairs or instances where a pre-existing key has a different value or a pre-existing value has a different key so for example avoiding scenarios like this: Fred: Luke Luke: Jim Jim: Jane and instead only allow these pairs to be written to my redis_instance: Fred: Luke Jim: Jane This is what I have: @api_view(['GET', 'POST']) def manage_items(request, *args, **kwargs): if request.method == 'GET': items = {} count = 0 for key in redis_instance.keys("*"): items[key.decode("utf-8")] = redis_instance.get(key) count += 1 response = { 'count': count, 'msg': f"Found {count} items.", 'items': items } return Response(response, status=200) elif request.method == 'POST': item = json.loads(request.body) keys = list(item.keys()) values = list(item.values()) for i in range(0, len(keys)): redis_instance.set(keys[i], values[i]) response = { 'msg': f"{keys} successfully set to {values}" } return Response(response, 201) not quite sure how to carry this out -

Django - Displaying content based on permissions in a class based view
I want to display an edit link on certain content if the user has permission to edit the content. I've done some research and it appears that the best way to do this is via the view.

How to properly migrate a monolith architecture app to a microservice app in Django
Today I come with this question probably to someone who has large experience in this. Basically what the title indicates. We have that app and we have to migrate it to microservices. We didn't find any solid approach (or we felt it like that) about this. What we ended up doing is creating 1 project per microservice (a single functionality related to a module app, in general) but then we had some problems because we already had a database to work with since this is already a functioning app. We had problems communicating with the existing models, so basically what we did was to point in every settings.py of the projects to the existing DB, and with python3 manage.py inspectdb, we grabbed the existing models. This approach ended up working, but we feel that is not the best approach. We had a lot of problems with circular imports and more. Is out there good practices about microservices with Django, and how to properly do it, like in most of the cases that we want to create something with the framework? If someone knows or has something we would really appreciate it! -

Complicated Neted Admin Inline
I have a complicated model, where playlists can be created on two levels: UserGroup and User. Further, these playlists are targeted to a specific weekday. So Users/UserGroups can have separate playlists for each day of the week. To manage the user playlists in the admin, I'm looking to add the User and UserGroup an inline of all weekdays, and under each weekday the inline of all songs (for that weekday). Hopefully the image below will clear this up a bit. To add to the confusion, the songs per a specific weekday should include both User songs and also UserGroup songs. My models: UserGroup name = models.CharField(max_length=255) User name = models.CharField(max_length=255) UserGroupSong file = models.FileField() weekday = models.ForeignKey(Weekday, on_delete=models.PROTECT) user_group = models.ForeignKey(UserGroup, on_delete=models.PROTECT) UserSong file = models.FileField() weekday = models.ForeignKey(Weekday, on_delete=models.PROTECT) user = models.ForeignKey(User, on_delete=models.PROTECT) inherit = models.BooleanField(verbose_name='Include songs from user-group for this weekday?') class Weekday(models.Model): day = models.CharField(max_length=255) # Pre-populated with values: Sun, Mon, Tue, Wed, Thu, Fri, Sat Any help will be greatly appreciated. -
